Nope not just door slamers. Only thing is that looks like a BBC in there and the chevy side of the race it sold out. But if it is a Ford Motor you will be more tham welcome to come race.
Also if you want to TNT your car Saturday night you can also do that. The TNT part is open to anyone on Saturday Night. Sunday is only open to the ones with a Ford or Chevy Racer Ticket.
